b1d6a2c624 cmdline module options can be disabled on "big" modutils
Allow module options on command line to be disabled on "big" modutils.

Config FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE is renamed to
FEATURE_CMDLINE_MODULE_OPTIONS and no longer depends on !MODPROBE_SMALL

(I'm not sure if disabling this is useful on "big" modutils, but at
least the macro can serve as a marker and ensure both implementations
of same feature have consistent behavior.)

b5b21126ca ash: improve / fix glob expansion
When using musl libc glob() a very long string can cause glob() to fail,
which leads to an out of memory error being raised by ash.

This can happen easily if a very long quoted string contains *, even
though no glob expansion should ever be performed on it (since it's
quoted).

Fix this by properly parsing control characters and escaping and only
accept unquoted metacharacters. While we're at it, unify this check for
libc and built-in glob expansion

065e988e7a modutils: fix config options dependency
module.aliases and module.symbols files have no use in modprobe-small
implementation. So FEATURE_MODUTILS_ALIAS and FEATURE_MODUTILS_SYMBOLS
will depend on !MODPROBE_SMALL.

The try_to_mmap_module() function is not called in modprobe-small.c,
so I will let FEATURE_INSMOD_TRY_MMAP depend on !MODPROBE_SMALL for
now.

Likewise, FEATURE_2_4_MODULES is not used by modprobe-small.

Anonymous ftpd login is useful even when ftpd authentication feature

To allow password-less connection user command line option '-a USER' is
added. This option specifies the system user to use when
'anonymous' username is given in USER command. No password is required
in this case.

49ecee098d tls: add 2nd cipher_id, TLS_RSA_WITH_AES_128_CBC_SHA, so far it doesn't work
Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;)

This change adds inevitable extension to have different sized hashes and AES key sizes.
In libbb, md5_end() and shaX_end() are extended to return result size instead of void -
this helps *a lot* in tls (the cost is ~5 bytes per _end() function).
